<p><em>Current version: 0.0.14</em></p>

<p>Angular RangeSlider is a directive that creates an interactive slider that allows a user to change model values.</p>

<p>It has been styled to match form elements styled by <a href="http://twitter.github.io/bootstrap/">Twitter's Bootstrap CSS framework</a>.</p>

<h4>
<a name="requirements" class="anchor" href="#requirements"><span class="octicon octicon-link"></span></a>Requirements</h4>

<ul>
<li>Angular (v1.0.8+)</li>
<li>jQuery (v1.7+)</li>
</ul>

<h2>
<a name="quick-example" class="anchor" href="#quick-example"><span class="octicon octicon-link"></span></a>Demo</h2>

<p>Take a look at the <a href="demo/">live demo page</a></p>

<p>Or the <a href="demo/legacy.html">legacy Angular demo page</a></p>

<h2>
<a name="quick-example" class="anchor" href="#quick-example"><span class="octicon octicon-link"></span></a>Quick example</h2>

<p>A basic slider with a range of 0 to 100:</p>

<pre><code>&lt;div range-slider min="0" max="100" model-min="min" model-max="max"&gt;&lt;/div&gt;
</code></pre>

<p>As the handles are moved the model values <code>min</code> and <code>max</code> will be updated in the parent controller.</p>

<p><img src="screenshots/slider.png" alt="Default example"></p>

<h2>
<a name="options" class="anchor" href="#options"><span class="octicon octicon-link"></span></a>Options</h2>

<p>Options are set as attributes on the <code>&lt;div range-slider&gt;</code></p>

<h3>
<a name="-two-way-bindings" class="anchor" href="#-two-way-bindings"><span class="octicon octicon-link"></span></a><code>=</code> two-way bindings</h3>

<p><code>min</code> - the minimum value the user can select (must be a number, can be a model property)</p>

<p><code>max</code> - the maximum value the user can select (must be a number, can be a model property)</p>

<p><code>model-min</code> - the model property for the min value, represents the position of the min handle</p>

<p><code>model-max</code> - the model property for the max value, represents the position of the max handle</p>

<p><code>disabled</code> - model property or boolean, disables the slider when <code>true</code></p>

<h3>
<a name="-attributes" class="anchor" href="#-attributes"><span class="octicon octicon-link"></span></a><code>@</code> attributes</h3>

<p><code>orientation</code> - slider orientation, default: 'horizontal' - options: 'horizontal' | 'vertical' | 'vertical left' | 'vertical right'</p>

<p><code>step</code> - amount to change the value by when moving a handle, default: 0</p>

<p><code>decimal-places</code> - the number of decimal places to round to, default: 0</p>

<p><code>filter</code> - a built-in filter to apply to the displayed values, for example <code>currency</code> or <code>currency:'$'</code></p>

<p><code>filter-options</code> - options to pass to the filter</p>

<p><code>pin-handle</code> - disable/hide one handle, default: null - options: 'min' | 'max'</p>

<p><code>prevent-equal-min-max</code> - prevent the <code>min</code> and <code>max</code> values from being equal. The <code>step</code> value is used to set the minimum difference, otherwise a value of <code>1</code> is used.</p>

<p><code>attach-handle-values</code> - move the value labels in sync with the slider handles when <code>true</code>, default: <code>false</code></p>

<h2>
<a name="some-more-examples" class="anchor" href="#some-more-examples"><span class="octicon octicon-link"></span></a>Some more examples</h2>

<h3>
<a name="using-model-properties" class="anchor" href="#using-model-properties"><span class="octicon octicon-link"></span></a>Using model properties</h3>

<p>The following properties are present in the scope:</p>

<pre><code>// set available range
$scope.minPrice = 100;
$scope.maxPrice = 999;

// default the user's values to the available range
$scope.userMinPrice = $scope.minPrice;
$scope.userMaxPrice = $scope.maxPrice;
</code></pre>

<p>So we can include the directive in the HTML like this:</p>

<pre><code>&lt;div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5"&gt;&lt;/div&gt;
</code></pre>

<p>As the user moves the min and max handles the <code>userMinPrice</code> and <code>userMaxPrice</code> will be updated in increments of <code>5</code> in real-time in the model.</p>

<h3>
<a name="using-filters" class="anchor" href="#using-filters"><span class="octicon octicon-link"></span></a>Using filters</h3>

<p>Continuing from the example above we can format the values displayed to the user as currency.</p>

<pre><code>&lt;div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency"&gt;&lt;/div&gt;
</code></pre>

<p>This will automatically be localised by Angular, but we can force it to be USD by passing this as an option:</p>

<pre><code>&lt;div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency" filter-options="USD$"&gt;&lt;/div&gt;
</code></pre>

<p>Alternatively you can use Angular's filter notation directly in the <code>filter</code> attribute, such as <code>filter="currency:'GBP £'"</code>, which would result in values like this: <code>GBP £7,500.00</code>.</p>

<pre><code>&lt;div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency:'GBP £'"&gt;&lt;/div&gt;
</code></pre>

<p><strong>NOTE:</strong> If the <code>filter-options</code> attribute is defined you **cannot** use Angular filter notation. You must only use the filter name in the <code>filter</code> attribute.

<h3>
<a name="making-the-slider-vertical" class="anchor" href="#making-the-slider-vertical"><span class="octicon octicon-link"></span></a>Making the slider vertical</h3>

<p>Simply add one of the following values to the <code>orientation</code> attribute: 'vertical', 'vertical left' or 'vertical right'.</p>

<p>This will create a vertical slider that is centred in it's parent element:</p>

<pre><code>&lt;div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical"&gt;&lt;/div&gt;
</code></pre>

<p><img src="screenshots/vertical.png" alt="Vertical example"></p>

<p>To left-align the slider use 'vertical left':</p>

<pre><code>&lt;div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical left"&gt;&lt;/div&gt;
</code></pre>

<p>And to right-align the slider use 'vertical right':</p>

<pre><code>&lt;div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical right"&gt;&lt;/div&gt;
</code></pre>

<h3>
<a name="disabling-the-slider" class="anchor" href="#disabling-the-slider"><span class="octicon octicon-link"></span></a>Disabling the slider</h3>

<p>If you have a boolean property in your scope you can simply change this value to <code>true</code> to disable the slider:</p>

<pre><code>$scope.sliderDisabled = false;
</code></pre>

<p>And then specify the property using the disabled attribute:</p>

<pre><code>&lt;div range-slider min="0" max="100" model-min="min" model-max="max" disabled="sliderDisabled"&gt;&lt;/div&gt;

// clicking this button will toggle the sliderDisabled value between true and false
&lt;button ng-click="sliderDisabled=!sliderDisabled"&gt;Toggle slider disabled status&lt;/button&gt;
</code></pre>

<p><img src="screenshots/disabled.png" alt="Disabled example"></p>

<h3>
<a name="pinning-a-handle" class="anchor" href="#pinning-a-handle"><span class="octicon octicon-link"></span></a>Pinning a handle</h3>

<p>If you would like only allow setting one value, effectively creating a single-value silder, set the pin-handle attribute to 'min' or 'max'. You may then omit the corresponding model-xxx property:</p>

<pre><code>&lt;div range-slider min="0" max="100" model-max="max" pin-handle="min&gt;&lt;/div&gt;
</code></pre>

<p><img src="screenshots/pinned.png" alt="Pinned example"></p>

<h2>
<a name="to-do" class="anchor" href="#to-do"><span class="octicon octicon-link"></span></a>To Do</h2>

<ul>
<li>Remove full jQuery dependency</li>
<li>Make it work in older Angular versions</li>
<li>Add option to move values with handles</li>
<li>Improve behaviour when model values are not valid (e.g. min is greater than max)</li>
</ul><h2>
<a name="known-issues" class="anchor" href="#known-issues"><span class="octicon octicon-link"></span></a>Known Issues</h2>

<ul>
<li>The slider restricts the model value when editing outside the slider (e.g. in an ) but the only notification is made to the <code>console</code>
</li>
<li>The min slider handle disappears behind the max slider handle</li>
</ul><h2>
